我公司粒状过磷酸钙生产采用圆盘造粒、回转式烘干的生产工艺,年生产一等品粒状过磷酸钙1.5万t。磷石膏因其有一定的粘性,所以在造粒过程中可提高过磷酸钙成球率。成品成球率可从原来的85 %提高到现在的95 %以上。从而使出厂成品合格粒度都在99%以上,成品的外观也得到了改善,颗 Our company granular calcium superphosphate production using disc granulation, rotary drying production technology, the production of first-class products of granular superphosphate 15,000 t. Phosphogypsum because it has a certain viscosity, so in the granulation process can increase the ball into the rate of superphosphate. Finished into the ball rate can be increased from the original 85% to now more than 95%. So that the finished product particle size are qualified in more than 99%, the appearance of the finished product has also been improved,
